CONTROLLER OF COPYING MACHINE

摘要

PURPOSE:To obtain copies of various contraction/magnification ratios from a long-size original by changing the original transport speed in response to the copying contraction/magnification ratio selected by a setting switch. CONSTITUTION:A central processing unit 13 reads a desired parameter out of an ROM12 and performs the processing based on the active signal sent from a copy mode selection switch 9 for long-size original as well as the signal sent from a setting switch 10 for copying contraction/magnification ratio. Then the unit 13 applies a speed instruction signal showing a speed of an original transport device suited to a desired contraction/magnification ratio to a driving circuit 15. As a result, a driving motor 16 for original conveyor belt is driven at a corresponding speed and in response to the working of a copy start switch.
